Global Positioning System Reference
In-Depth Information
software functions are needed to associate position with information for each user
and appropriate human machine interfaces (HMI), particularly for those with
special needs (e.g., haptic technology or technology using the sense of touch for
blind people). Figure 5.2 shows a blind person exploring a digital map using a
haptic interface, and Figure 5.3 shows a blind volunteer using a personal guidance
system with DGPS positioning and a digital map attributed with spoken voice
information.
